The choice with the small ship fitting in small spaces but hard to control while the big ship is much easier to control but will collide with everything feels intuitive and interesting. The graphics are simple but work just fine. The level design is Ok but there are places where you have to make a choice simply not knowing that one of the paths will be blocked further on, so you've essentially already died, which is a bit annoying. A bit too hard for me but good job, keep going! :-)
